Look them up. Let me know the part number and I can get them to you. Possibly free, if I can get ahold of some and if you come pick them up at my place. I'm in Belmont.
Otherwise, Quality Fasteners in Bessemer City, NC can get you anything you want. Literally.
Automotive Fasteners has a store in Winston-Salem... http://www.automotivefasteners.com/contact.html
They might not know what thread and length you'll need. Bring an old bolt in, or find out beforehand.
